What are the recommended best practices for origin servers to minimize 502 errors when used with CloudFront?

Best practices for origin servers include ensuring high availability, configuring appropriate timeouts, handling HTTP requests gracefully, and returning valid HTTP responses. Regularly monitor your origin server's performance and resource utilization. Implement robust error handling and logging on your origin. Ensure your origin server can scale to handle the traffic requested by CloudFront. For custom origins, consider using a load balancer to distribute traffic and provide redundancy.
